Factor analyses for the Örebro Musculoskeletal Pain Questionnaire for working and non-working patients with chronic low back pain

The ÖMPQ has good psychometric properties to predict return to work in patients with acute low back pain. Although it is used in patients with chronic back pain and non-workers, there is no evidence on the factor structure of the ÖMPQ in these populations. This is deemed an important prerequisite for future prediction studies.
